m16a1/ar15a1 clone

Bushmaster makes a nice A1 upper that's got the teardrop FA, brass deflector, and can be ordered with M4 feedramps. I'm planning on my first AR using one with a 16" midlength setup. As much as I've resisted an AR, the idea of building my ideal carbine is too tempting.

NOTE: The Bushmaster/DPMS/Fulton Armory A1/C7 uppers are the black anodized finish, not the XM gray like the NDS lowers.

M16A1s don't have brass deflectors.



You'll also need a thin barrel with a 1/12 twist. The C7 is simply an M16A2 with an A1 sight/handle and full auto trigger group. It retained the M16A2 barrel, stock, grip, handgaurds and also had the brass deflector.

My bad. The BM/FA uppers are the C7 uppers while the Colt ones from Apex are true A1 uppers. If you're looking for a modern barrel to shoot all weights of ammo, FA makes the pencil barrels in 20" and 16" in a 1:8 twist rate.

EDIT: Suggested the 'Legacy' upper and FA barrels as it's closest to what he is looking for (aside from brass deflector) aesthetically and can handle a wider variety of ammo; there's way more than just M193 out there these days. Hahaha.

I just got my upper in the mail and my plan for it is to build an 'A1 for 2012'.

Can't wait to see how it turns out. You are going have really cool throwback piece that will garner quite a bit off attention when you take it out shooting.

Green Mountain Barrels makes 20'' A1 barrels with the "original" 1:12 twist rate. As a concession to modern times, those do have M4 feedramps.

I'll have to look into the GM barrels. That's pretty interesting. I knew BM would do M4 cuts in their C7 receivers if you called and ordered them. I'm deciding on a full A1 build with the black NDS lower and triangle or 'prototype' handguards or an 18" RA barrel and the MI SS-12 forend. I think a modern interpetation of the A1 (light, simple, reliable) would be a fun build. D@mn, I have a feeling I'll have to buy 2 lowers when I go to order them... Haha.
